When the width of the cut paper strips is large, the second driving mechanism 34 drives the mounting block 32 to slide, so that the first traction roller 33 and the second traction roller 42 can apply certain pressure to the surface of the paper roll to clamp the paper roll, the third driving mechanism 63 can drive the second conveying roller 62 and the second traction roller 42 to synchronously and intermittently rotate so as to convey the paper roll, the first driving mechanism 53 can adjust the movable cutter 52 to do reciprocating motion at a lower frequency, so that the front end of the paper roll is cut off in the moment that the front end of the paper roll is contacted with the workbench 2, and the phenomenon that the paper roll is inconsistent with the workbench 2 and is bent and deformed to cause the inaccurate width of the paper strips cut by the movable cutter 52 is avoided. When the width of the cut paper strip is small, the bending deformation amount of the paper strip is small, the second driving mechanism 34 drives the mounting block 32 to slide, so that the first traction roller 33 retracts into the first mounting groove 31, the second traction roller 42 cannot apply pressure to the surface of the paper roll, at the moment, the third driving mechanism 63 can drive the second conveying roller 62 to rotate non-intermittently to convey the paper roll, when the movable cutter 52 advances and cuts the paper roll, the front end of the cut paper roll is abutted against the movable cutter 52, because the second conveying roller 62 rotates non-intermittently, the paper roll can push the tension spring 72 and expand outwards, when the movable cutter 52 retracts, the paper roll is rapidly conveyed under the elastic potential energy of the tension spring 72 and abutted against the workbench 2, so that the first driving mechanism 53 can adjust the reciprocating motion of the movable cutter 52 at a high frequency to rapidly cut the front end of the paper roll, the production efficiency is improved.
The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
